Good Morning America, How Are Ya?

Just in case you weren’t sitting inside on this beautiful late-summer morning watching television over your breakfast bagel, you can see today’s Good Morning America segment on the Freakonomics paperback, here.



The Economics of Doing What You Love

Marketplace, the economics program on National Public Radio, is running a fun series this week — asking economists to reflect on how thinking like an economist can shape your personal decisions. While the pieces are pretty light, it’s also a neat opportunity to teach some simple economics. Yesterday, it was my turn, and so I focused my economic lens on my marathon training. And thinking like an economist means thinking in terms of opportunity cost.



Vote for Our Songwriter

Jonathan Mann, the resident Freakonomics songwriter, is currently a finalist in mobile query service ChaCha’s music video contest.



Statistical Slumps

It was during a trip to the Boston Science Museum that I had an idea about calculating statistical slumps.



To Catch a Criminal, It's All About Presentation

Dallas’s police department changed the way it lines up its suspects for identification. Instead of the common “six pack” method where the victim looks at six photos at once, detectives (blind to who the suspect is) started showing the photos one at a time.



Hitting Sports Cheats in Their Wallets

A reader named Christopher Rumney writes in with an interesting idea for how to discourage illicit performance-enhancing drugs in pro sports. Perhaps something like this has already been proposed, but I’ve not heard of it, and it’s certainly an interesting idea — although any players’ union in its right mind would likely rather blow itself up than submit.



Freak Morning America

We wanted to let you know that Dubner is scheduled to appear on Good Morning America this Thursday, Aug. 27.



A Profile of the Smile Train founder

This month’s Harvard magazine has a nice piece on the founder of the Smile Train, Brian Mullaney.
I love the way he runs his organization, and the way he tells it like it is.



Nudges by Chopstick

Brian Wansink and Collin Payne recently examined the relationship between Body Mass Index (BMI) and eating behaviors at all-you-can-eat Chinese buffets.






Why the Israeli Organ-Harvesting Story Is Probably False

A strange story has broken out in Sweden and Israel, with an article in Aftonbladet, a Swedish newspaper, by a journalist named Donald Bostrom.
According to The Times, Bostrom’s article “accuses the Israeli Army of harvesting organs from Palestinians wounded or killed by soldiers.”



Chianti as Collateral

Italian banks may soon accept fine wines and dry-cured hams as collateral on loans.




Aliens and Cat-Food Monopolies

In the movie District 9, the aliens (“prawns”) have developed a tremendous addiction to cat food. A Nigerian gangster lives in the prawns’ preserve and has a monopoly on the sale of cat food to the prawns. How can he maintain his monopoly and what barriers are there to entry by other sellers?



Bring Your Questions for Buzz Aldrin

Aldrin has agreed to take your questions — about NASA, walking on the moon, the value to society of space exploration, or anything else you can conjure — so ask away in the comments section below. As with all Q&A’s, we will post his answers here in a few days.



When Justice Is Too Far Away

Megwalu emphasizes the importance of resolution on the ground, saying, “people may appreciate the arrest of persons like Thomas Lubunga of the DRC (currently held by the ICC), but if his arrest does nothing to rebuild trust in affected communities, and/or does nothing for the lady who lost a son to his brutal tactics but never gets to hear/see him account for his crimes, then little has been gained on the ground.”



Usain Bolt Is No Takeru Kobayashi

I blogged last week about how progress in lowering the world record in the 100-meter dash has been extremely slow, even with the improvements in track surfaces, training techniques, steroids, etc. The world record has been lowered at an average of 0.1 percent per year over the last 40 years.



Will Brazil Binge on Oil?

Brazil, a longtime leader in developing alternative energy for its transportation sector and its electricity, has recently discovered a truly gigantic supply of oil under its ocean waters.



The Bottom Line on Top-Speed Trains

Edward Glaeser (over at the Economix blog) and I have been writing about high-speed rail (HSR) over the past couple of weeks; he just finished his cost-benefit analysis of a hypothetical Dallas-Houston line with a look at land-use impacts. His overall conclusion, even making some very generous assumptions in favor of rail, is that the line would be a net cost to society of at least $375 million per year. This includes HSR’s potential environmental benefits as well as the direct gains to riders.
A couple of caveats are in order.



How Impressive Is Usain Bolt? A Freakonomics Quiz

This is in spite of the fact that there have surely been technological advances in tracks and shoes, as well as expanding knowledge of weight training and fitness. The world’s population has increased substantially, as have nutrition levels, especially in developing countries.
The biggest puzzle to me is not how remarkable Usain Bolt is, but rather why it’s been so hard to get people to sprint faster.



Teach Your Teachers Well

Of the (very) many large topics on the Obama administration’s to-do list, one that has slipped off the radar of late is education reform. I assume Arne Duncan et al. are working hard and will retake the spotlight eventually, maybe even in a few weeks when a new school year begins. It will be interesting to see how much attention is paid to one of the most important, albeit touchiest, topics of school reform: teacher skill.



Shocking Unemployment Numbers

I don’t usually write about macro things. But a journalist asked me about the duration of unemployment, and I checked out how this recession compares to previous ones.



Bank Robbers' Hours

According to the FBI’s recently released second quarter Bank Crime statistics, bank robbers are most likely to rob a bank between 9 a.m. and 11 a.m. on Friday; more robbers stated their demands verbally than by passing a note, and only 4 percent of incidents involved violence. The FBI also noted that, despite the recession, there were fewer bank robberies than last year.



Anti-Public Intellectuals, or Public Anti-Intellectuals?

Over at The Atlantic, Richard Posner writes:
I am concerned with the fact that academic economists, when they become either public officials or public intellectuals (like Krugman), leave behind their academic scruples.
In a later paragraph, he expands on his theme, turning to:



Why Is Phone Fidelity So Poor?

I am the first to say this and surely I will not be the last, but: isn’t it strange that with all the technological improvements in our lives in the past few decades, the audio fidelity of so many of our phone calls is so abysmal?



Quotes Uncovered: Who First Took Things With a Grain of Salt?

A while back, I invited readers to submit quotations for which they wanted me to try to trace the origins, using The Yale Book of Quotations and more recent research by me. Hundreds of people have responded via comments or e-mails. I am responding as best I can, a few per week.



How Much Do Protests Matter? A Freakonomics Quorum

Iran’s citizens take to the streets en masse after a disputed election. Gay men in Salt Lake City hold a kissing protest. Members of the Westboro Baptist Church voice their anti-just-about-everything views to military funerals and elsewhere.
Beyond the media attention they inevitably garner, what do protests actually accomplish?



Fight Spam With Pennies

Fight spam by donating to your favorite charity. That’s how researchers at Yahoo are hoping to convince people to put a virtual one-cent stamp on their outgoing e-mails. Sending a penny-stamped e-mail through Yahoo’s (not yet released) CentMail program would automatically mark it as “real mail” and get it past any spam filters.
